# zhdanskyi/java-projects architecture

> Architecture diagram of the GitHub repository zhdanskyi/java-projects, generated by GitDiagram from its file tree, README and a sample of source files (last updated 2026-09-26). It is an AI-made overview: check details against the source.

## Overview

This repository is a collection of independent Java/Kotlin learning projects, not one integrated product. The sampled code shows separate examples for movie lookup/export, shop database operations, school staffing, and a small PDF-and-logging UI. The movie controller’s HTTP, parsing, and CSV behavior and the school example’s calls are visible in source; other wiring is omitted where the entry point or implementation was not sampled. The empty README provides no additional product-level workflow or capability map.

Main entry points: [`TiendaDB/src/main/java/controller/Controller.java`](https://github.com/zhdanskyi/java-projects/blob/master/TiendaDB/src/main/java/controller/Controller.java) (Shop controller), [`API/src/main/java/controller/APIcontroller.java`](https://github.com/zhdanskyi/java-projects/blob/master/API/src/main/java/controller/APIcontroller.java) (Movie API controller), [`HERENCIA2/src/Main.java`](https://github.com/zhdanskyi/java-projects/blob/master/HERENCIA2/src/Main.java) (School demo), [`kotlinn/src/Main.kt`](https://github.com/zhdanskyi/java-projects/blob/master/kotlinn/src/Main.kt) (PDF UI and workflow)
